DRIVING MECHANISM FOR COP AND BOBBIN WINDERS.

SPECIFICATION forming part of Letters Patent No. 486,258, dated November15, 1892..

Application filed November 27, 1891. Serial N0.413,19'7. (No model.)

To all whom it may concern.-

Be it known that we, OSWALD LEVER and WILLIAM S. GRUNDY, citizens of theUnited States, residing in the city of Philadelphia, State ofPennsylvania, have jointly invented certain new andusefulImprovementsinDriv- 1n g Mechanism for 00p and Bobbin Winders, ofwhich the following is a full, clear, and exact descr ption, referencebeing had to the accompanymg drawings,for1ning a part of thisspecification.

Qur invention relates to the driving mechanism for cop and bobbinwinders; and it consists of the combination and arrangement, withconical friction driving-gearing, of mechanism, hereinafter described,whereby the length of vibration of the thread-guide over the spindle orbobbin and the rapidity of rotation of the spindle or bobbin as the yarnis being wound thereon is regulated, and in the construction of the copand bobbin forming device and mechanism to raise and lower the same.

In the accompanying drawings, illustrating our invention, Figure 1 is aside elevation of a cop-winder with our improved driving mechauismadapted thereto. Fig. 2 is a plan View of the conical frictiondriving-gearing, the cam mechanism, and the shaft connected to the loosebelt between the conical rollers. Flg. 3 is a side view of the mechanismshown in Fig. 2. Fig. 4 is a detached side view of the main shaft,cog-gearing, and the ends of the conical rollers with the loose beltbetween them. Fig. 5 is a front view, and Fig. 6 a plan View of thevertically-adjustable cop-forming device, which is operated through theconnecting arms shown in Fig. 1 by the cams shown in Figs. 1, 2, and 3,mounted on the actuating-shaft. Fig. 7 is a side elevation, and Fig; 8 avertical sectional view of the mechanism shown in Fig. 5, and Fig. 9 areviews in elevation and section, respectively, of the bobbin.

Mounted on the frame A (see Fig. 1) is shown cop-winding mechanism, inwhich for the spindle 2 may be substituted bobbin-winders such as shownin elevation and in section in Fig. 9. Thiscop-winding mechanism is thatfor which we have filed application for Letters Patent March 2, 1891,Serial No.

383,499 but any other cop-winding mechanism having similar features maybe used in connection with our invention constituting the subject-matterof this application. The driving-shaft (marked A) of the cop or bobbinwinder is actuated by a driving-belt 8, passing around a pulley 9,driven through the gearing carried by the shaft B, which latter has itsbearings in the frame A of the machine at the base thereof. Mounted uponthis shaft B are two cams 4, which play between cam-pins 5 5 on arms 3,which latter have a slotted connection with arms 7, carrying thevibrating yarn-guide T, which, being made as usual, need not beespecially described.

In Fig. 4 is shown a detached view of the cog-gearing on theactuating-shaft B, which gears with a cog-gearing on the end of theshaft which carries the driven conical friction-roller.

The connection between the driven shaft B and the vibrating thread-guideis shown in side view in Fig. 1. In side View in Fig. 3 and in plan viewin Fig. 2 is shown the shaft B, which drives the said shaft 13' throughthe worm-gearing R r, in which figures G represents the driving conicalpulley and L the driven conical friction-roller, the shafts of which areparallel with each other, they being at such distance apart that the twopulleys, each of which has its smaller end opposite the larger end ofthe other one, have their tapering surfaces free from contact with oneanother, but sufficiently close to grip between them a narrow endlessbelt M, arranged loosely around the driven pulley L. The details of theconstruction of this transmitting motion need not be more particularlyherein described, as the same in its essential details will be foundshown and described fully in Letters Patent to W. E. Laird, No. 299,231,dated May27, 1884, and in patent to G. F. Evans, No. 374,296, datedDecember 6, 1887. It is sufficient to say here that it will be observedthat the driving-pulley G will operate the driven pulley L in a reversedirection by pressure of the pulleys on the belt M between them, andthat as said belt is moved toward the larger or smaller end of thedriven pulley L said pulley will have its velocity increased ordiminished, while the motion of the driving-pulley G will be uniform,and that the speed of the shaft B driven by the driven pulley will beincreased or diminished without stopping the motion of the machine, bymeans of mechanism which will slide the belt M on the periphery of thedriven roller. This part of our invention consists of mechanlsm toaccomplish this end automatically, as required in Winding the yarn uponthe varying thickness from end to point of the cop or bobbin. Thisautomatic mechanism consists of a rod N, which is pivot-jointed at oneend at m to a belt-sleeve g, which hangs by a recess upon a short arm a,mounted in the frame of the machine, and which serves as a guiderodalong which the rod N pulls the belt M backward and forward on theperiphery of the driven roller L. The shaft of the driven rollercommunicates power, as before mentioned, to the actuatingshaft B, whichis provided with a worm R, gearing into a worm-wheel r, mounted on shaft13, carrying the cam 6, the face of which plays between two pins 5 s atthe extremities of the slot S in the rod N, whereby the latter isreclprocated. Said rod N is provided with a tension-weight, consistingof the bob T, attached by a chain 15, passing over the pulley 2, fixedto the frame of the machine.

The cop-forming device is shown in side view in Fig. l and in detail inthe four separate views constituting Figs. 5, 6, '7, and 8. It isconstructed of a frame orhousing D, secured to the frame of the machine,the face of which is slotted at d (see Fig. '7) at about half its heightand is provided with a projectlon (Z at its base. Within this housing orframe slides vertically a bar E, to which is pivotally hinged at d twoarms I) b, which are both slotted at c c, and through which slots passesa set-screw c, which thus enables the arms Z) Z) to swing laterally uponthe pivot 61 and adj ustably brought closer together or farther apart,as maybe desired, and upon these arms Z) Z) are spindles ct, extendingoutwardly and at an angle horizontally, upon which spindles freelyrotate two conical rollers a a. At the lower end of the bar E ispivotally connected at d a finger F, the inwardly-extendmg base of whichhas between its top surface and the base of the bar E a spring (i whichtends to throw the finger inwardly, so that when it is raised by thehand, the lateral bar cl thereon will naturally drop into the recess clin the housing D. By means of this arrangement of mechanism thevertically-slid- 1ng bar E, carrying the cop-forming conical rollers,may be elevated by lifting the finger F,and it remains in an elevatedposition,owing to the lateral bar (1 on said finger dropping into therecess (Z of the housing or frame. hen it is desired to lower thecop-forming rollers, the finger F is given an outward pull,

and the bar E therefore falls down until the said lateral bar (Z'strikes the projections (Z csaess on the housing D, which thus limitsits descent.

Having thus described our invention, what we claim as new, and desire tosecure by Letters Patent, is-

1. The combination, with the reversely-conical pulleysL and G, of theendless belt or band M, arranged loosely around the driven pulley, thebelt-shifter c, the fixed rod 77., upon which said belt-shifter isguided in its reciprocation, the rod N, pivoted at m to the same, thedriven shaft B, connecting actuating-gearing between said shaft B androd N, operating to reciprocate the said rod N slowly, the shaft B,driven thereby, and theyarn-guide and its actuating mechanism consistingof the vibrating slotted arm 7, pivoted in the frame of the machine andactuating said guide, the rod 3, the cam 4, mounted on said shaft B andoperating to reciprocate the said rod, substantially as described.

2. The combination, with the reversely-conical pulleys L and G and theendless belt or band M, arranged loosely around the driven pulley, ofthe belt-shifter g, the rod N, pivoted to the same, and mechanism toreciprocate the said rod N slowly, consisting of a counterbalancingdevice to move the said rod N in one direction, and cam-pins s s ousaidrod N, the slot S between the same, the cam 6, its shaft anddriving-gearing, and the shaft B and worm-gearing, said parts operatingto move the rod N in the opposite direction, substantially as described.

3. Bobbin-forming mechanism consisting of loosely-mounted conicalrollers a a, bearings therefor consisting of arms b b, pivoted at theirlower ends at d and provided with roller-shafts a a, set at an anglethereto, and vertically-sliding supporting-frame E, lateral slots 0 c insaid arms I) b, and a set-screw c, passing through said slots into theface of the supporting frame E, substantially as described.

4. The combination, with a fixed frame D, of a frame E, adapted to slidevertically therein, provided with a finger F, hinged to the base of saidframe E at d and having a spring d between it and said frame, and withpro jecting pin d, said fixed frame D being provided with a projection(1 acting as a stop for the downward descent of the finger F, and havinga recess cl, into which the projecting pin d will pass on the upwardrise of the tinger and acting as a locking device therefor,substantially as described.

In testimony whereof we have hereunto affixed our signatures this 17thday of October, A. D. 1891.
